Daehyun
best:
Damchu - he created the nickname and called himself damchu. it is a combination of his name and his favorite youtube singer, Sam Tsui.
worst:
Busan Wonbin - like hell, i cringed so hard. he looks nothing like Wonbin and Wonbin looks nothing like him. idk whose idea is that. maybe the company, maybe the fans during his debut era. i personally hate that name. even his other nickname "daebutt" is better to me lmao
